# SHARED across every C provider (clang, future gcc): all C providers stage the
# same libc into the same sysroot so they present one, identical C ABI. The LLVM
# half of the coupling is pinned separately by the
# `providers/c-clang/llvm` submodule commit.
#
# `nanvix_tag` is injected into the toolchain build as `Z_NANVIX_RELEASE_TAG`,
# which downloads the matching Nanvix release tarball and stages it into the
# sysroot. Bumping any value here is a reviewed commit that yields a new SDK
# image version.
